Can CPU frequency alone damage a CPU

daniel84uk · Sep 25, 2014

Hello all.

This is the first time ive ever overclocked, Im using a 3770k on a p8p67 delexe board. H100i

Im at 4.8ghz HT is on and 1.23v but its using even less according to CPU-Z only 1.216! This seems incredibly low from what ive been reading online. prime95 has been on 20 minutes so far. Max temp ive seem is 82c

Before i go further is temperature the only factor to consider regarding CPU degradation? ie is 5ghz as damaging as 4.5ghz all other things being equal like voltage and temp?

Ill delid it before going any further, as the temperatures are getting pretty warm. but actually, all i use the machine for is flight simulator and after 30 minutes on that the temperature max to only 76c.

Thank you all

While yes, the frequency can possibly damage a CPU, chances are low as long as reasonable care is taken, as you appear to be doing, monitor temps and keep voltage reasonable. If it get's too hot, the CPU itself will throttle itself and if heat rises to high, shut itself down

Higher frequency means higher performance which corresponds to higher voltage. So bumping up your voltage will cause your components to heat up and too much heat will fry them, but on the contrary good cooling solutions will remove this problem for even if you bump up your voltage to boost performance your components are in the reasonable temp which will prevent them from damaging.

Pay attention to your temperature always.

I dont think you both quite understand where im coming from

I know the higher the temperature the more degradation. And i know the higher the frequency the more voltage that is needed to keep it stable.

Ill ask another theoretical question first.

would 5ghz @1.3v 100% load be hotter than 4.5ghz @ 1.3v 100% load

Or is it purely voltage that depicts the temperature?

Thanks again.

It is about 95% voltage that determines temps. I actually dropped temps when raising my clock from 3.35 to 3.43 at the same voltage. Voltage almost always dictates where your temps are going to be.

That's not true cpt... Temperature will rise or fall linearly with frequency change. Where as temperature will rise or fall with frequency change and different voltage values, at different predefined rate. It can be predicted roughly as follows.

P(or temperature) = C V^2 f C is capacitance, f is frequency, and V is voltage

Yes 5.0ghz will run hotter than 4.5 at the same voltage value

CptBarbossa · Sep 26, 2014

Notice I said 95% has to do with voltage. Yes you will see temperature fluctuation with frequency changes, but it will not be anywhere near as high as voltage raises.

I understand, but your ratio is off, it's not 95 percent
